A Leaky Exchange offers a porous reinterpretation of the intertidal zone of the beach. Neither land nor sea, the intertidal zone is a site of porous encounters that are evermoving and ever changing. This constant state of flux allows hybrid permeations between human and non-human phenomena – revealing strange entangled, and interactive ecologies. Taking the intertidal zone as a starting point, artists Billie Baker and Emma Pinsent examine affective leakages between human and non-human material bodies. Through site-responsive sculptural and photographic processes, each artist implicates their practice in a kind of ecology with the intertidal zone, engaging in material and semiotic processes that transform, penetrate, erode, and saturate experimental outcomes.
